Sir Richard Branson is at it again. The billionaire who always acts just like you’d want a billionaire to act has said that it is one of his goals to start a population of humans living on Mars. It isn’t the craziest idea on the planet since there are actually other entities working on the same thing.

In an interview on CBS This Morning, Branson pointed out that in the history of mankind, only around 500 humans have been into space. He wants those numbers to skyrocket — pun intended. First things first, Branson is working diligently to get his Virgin Galactic operations off the ground.

Next year, people will be able to take a two-hour flight into space thanks to Virgin Galactic. The cost is $200,000 per person, but that is just the beginning. Within 20 years, Branson said, he expects space travel to be commonplace. Over those next two decades, technology will improve, costs will decrease, and hopefully economies of scale will emerge to allow much more mainstream space flight possibilities.

Eventually, and in his lifetime, he hopes there will be the technology to send people to Mars. This is something that other companies and agencies also believe is possible. One initiative is even to have a global reality show set there, where inhabitants are told they can never come back to Earth.

Branson believes the decision to remove Shuttle missions from NASA‘s docket and let private enterprise take over was the right decision. Since then, companies like Virgin Galactic and SpaceX have increased their presence in this exciting industry. And ultimately, it has meant traveling into space will come within reach of most people alive today.
